PURPOSE: Despite recent progress in the procedures of revascularization, acute limb ischemia continues to account for a wide variety of complications, culminating very often in limb loss or death. These poor results after treatment of acute limb ischemia still remains a major challenge in vascular surgery. METHOD: To evaluate the clinical characteristics and risk factors for early limb loss in acute limb ischemia, the clinical data of 87 limbs (8 upper and 79 lower limbs) in 83 patients. that underwent revascularization for acute limb ischemia at Yeungnam University Hospital from January 1995 to February 2003 were analyzed retrospectively. A Log-Rank test of Kaplan-Meier method and Cox proportional hazard analysis were performed to identify those main effects predictive of amputation free survival. RESULT: The patients, 78 males and 9 females, ranged from 30 to 83 years of age, with a mean age of 67. The highest incidence occurred among people in their 50s and 60s. The underlying causes of acute limb ischemia were arterial embolism in 42 limbs (42/87, 48.2%), arterial thrombosis in 36 (36/87, 41.3%), bypass graft occlusion in 9 (9/87, 10.3%). The primary sources of embolism were cardiac origin in 25 cases (25/42, 59.5%), aneurysmal origin in 2 (2/42, 4.8%) and unknown origin in 15 (15/42, 35.7%). As for the severity of ischemia according to SVS/ISCVS classification, 40 limbs (40/87, 46.0%) were classified as category IIa, 39 (39/87, 44.8%) as category IIb, and 8 (8/87, 9.2%) as category III. For the treatment, 66 thromboembolectomies (including 20 cases treated with intraoperative thrombolytic therapy), 19 arterial bypasses and 2 catheter directed thrombolytic therapies were performed. There were 13 major amputations and 8 mortalities at 6 months after revascularization. Cumulative 15 day, and 1, 2, 4, and 6-month amputation-free survival rate of all survival patients were 88.8%, 85.7%, 83.9%, 83.9% and 81.4% respectively. Among the univariate analysis of 26 clinical variables, 10 factors were identified as being associated with amputation-free surviva: age (P=0.01), preoperative tissue gangrene (P=0.03), preoperative skin color change (P=0.00), preoperative muscle status (P=0.00), preoperative motor and sensory deficit (P=0.00, P=0.00), severity of ischemia by clinical category (P=0.00), symptom duration (P=0.02), length of occlusion (P=0.01), and cause of occlusion (P=0.01). In multivariate analysis, age (P=0.04), and preoperative skin color change (P=0.00) predicted a poorer response to therapy. The major limb amputations were performed in 2 limbs (2/41, 4.9%) of the emboli group, and 11 limbs (11/42, 26.2%) of the thrombi group. For the limb with thrombosis, the major limb amputations were performed in 9 limbs (9/26, 34.6%) of the thromboembolectomy group and in 2 limbs (2/16, 1.3%) of the arterial bypass group. CONCLUSION: These results suggest that prompt and appropriate treatment is critically important in the management of acute limb ischemia. In thrombi cases Especially, a more aggressive surgical approach may be necessary for limb salvage.

In the treatment of this complicated diabetic foot patient, we need an effective treatment principle because the complicated diabetic foot patient needs a longer hospitalization period and suffers from more frequent recurrences. We reviewed 43 diabetic foot patients who were treated in our department during the past 4 years. The 43 patients were divided into 4 groups according to their combined complications. Group A was the simple diabetic foot group(no complication group, n = 17). Group B was the diabetic foot group combined with the extensive cellulitis(n = 9). Group C was the diabetic foot group combined with the peripheral vascular disease(n = 8). Group D was the diabetic foot group combined with the renal failure(n = 9). As a results, wide range of reconstructive methods can be selected in the simple diabetic foot group. In group B, early and wide debridement was important to control the infection and later flap reconstruction was appropriate. In group C, the bypass operation should be desperate before improving the circulation of lower extremities, and therefore we successfully reconstructed the foot with various metohds including plantar V-Y advancement flap, considered as the most useful in our series. In group D, recurrence was more frequent and lower extremity amputations above the ankle level couldn't be avoided in spite of many operations and longer hospitalization. Therefore consideration of early amputaiotn is recommended for the effective treatment of this group.

Nesidioblastosis is a term that describes the prolonged differentiation of the Langerhan's islet cells from the epithelium of the pancreatic duct. Islet cell lesions accompanied with hyperinsulinemic, 80% are found to be benign islet cell tumors. In additional 10% are malignant and the remaining are nesidioblastosis. Children are usually affected and develop hyperinsulinemic hypoglycemia, but it is rare in adults. Only 20 cases has been reported worldwide and 6 cases in Korea. A 41-year old man & 42-year old woman was admitted due to intermittent hypoglycemic symptoms, that had been relieved by carbohydrate ingestion. Hyperinsulinemic hypoglycemia was documented during prolonged fasting. Under the presumptive diagnosis of insulinoma, Abdominal CT, Celiac angiogram and percutaneous transhepatic portal venous sampling were done, but we could not find any definitive mass. 85% of the pancreas & 88% of the pancreas was removed respectively. Pathologic examination of the resected pancreas revealed irregularly sized islets and scattering of small endocrine cell clusters throughout the acinar tissue and ductuloinsular complex.

Antibiotics related colitis is a well recognized disease entity which in its severest form may result in pseudomembranous colitis, whereas in another form, acute hemorrhagic colitis without pseudomembrane, related to the use of penicillin-type antibiotics is rarely reported. The clinical features of hemorrhagic colitis associated with antibiotics was characterized that the bloody diarrhea, often with abdominal cramping pain begins 2~7 days after starting the antibiotics and rapidly recovered after its withdrawal. Pathogenesis of this disease is not entirely clear. It has been believed that right-sided hemorrhagic colitis is one of the main forms of colitis associated with antibiotics, especially ampicillin derivatives or cephalosporin, but recent reports presented left-sided colitis. We experienced 2 cases of hemorrhagic colitis developed on the left colon after the introduction of quinolone.

A lymphangionma is a rare benign tumor occuring in the gastrointestinal tract, which is composed of lymphatic vessels of various size. A sharply demarcated smooth, soft, cystic submucosal tumor which is easily compressible and covered with normal mucosa is a characteristic ally an endoscopic feature. This lesion is considered to be a benign lesion, which does not need to be treated, but in cases that involve risk of any complications or symptoms, the lesion needs to be removed. Servral endoscopic treatment methods for a symptomatic lymphangioma have been introduced, but accompanying risk of complications, such as bleeding or perforation were reported. As complete removal of a lymphangioma is impossible due to its broad base, a newly developed unroofing method is presented to be effective and safe for resection of a large lymphan-gioma. Recently, 2 cases were experienced involving a lymphangioma in the large intestine, which was removed successfully by colonscopic unroofing therapy.

Neonatal hyperthyroidism is a very rare disorder occurring typically in the offspring of patients with Graves' disease or chronic thyroiditis. It is caused by the transplacental passage of thyroid stimulating antibodies (TSAb) from the mother to the fetus. There has been few reports of neonatal hyperthyroidism associated with congenital anomalies. We experienced a case of neonatal hyperthyroidism with unilateral microtia and agenesis of external auditory canal in a female neonate born to a mother who had euthyroid but with a thyroid stimulating antibody. The patient was presented with unusual alertness, tachycardia, tachypnea, watery diarrhea, periorbital swelling and exophthalmos. Diagnosis was made by thyroid function tests and TSAb. She was treated with Lugol solution, PTU and propranolol. New she is 6 months old and in good condition with no symptoms of hyperthyroidism.

Foreign body granuloma is a chronic, proliferative, inflammatory reaction caused by persistent poorly biodegradable tissue irritants. Currently, many injectable materials are being used extensively for soft tissue augmentation. Although considered biologically inert, these materials can evoke adverse reactions such as foreign body granuloma. Mainly these complications are a result of the use of unproven products injected by unlicensed or unqualified practitioners. Here we report a case of foreign body granuloma in the left lower eyelid secondary to injection of extracts from safflower seeds.

BACKGROUND: It is well known that patients with atopic dermatitis are prone to cutaneous infections, and especially superficial fungal infection. However, a study on the relationship of superficial fungal infection in atopic dermatitis patients has not yet been performed in Korea. OBJECTIVE: The purpose of this study is to evaluate the relationship of atopic dermatitis to superficial fungal infection in Koreans. METHODS: We examined for evidence of superficial fungal disease in 2,153 atopic dermatitis patients and we compared the findings to those of 126,777 non-atopic dermatitis patients who visited the Department of Dermatology of Chung-Ang University from January 2003 to December 2007. RESULTS: Superficial fungal infections were more common in the atopic dermatitis patients (6%) than in the controls (2.5%) (p<0.05) and especially in the age group of the 1st and 2nd decades (p<0.05). The seasonal prevalence of superficial fungal infection was high during summer for both groups (38% vs 44%, respectively). The most common site of fungal distribution was feet (Tinea pedis) for both groups (42.5% vs 28.1%, respectively). The prevalence of coexisting superficial fungal infection was not significantly different in both groups (38.3% vs 39.9%, respectively). The most common isolated organism was Trichophyton rubrum in both groups (52.7% vs 38%, respectively). CONCLUSION: The study shows that the prevalence of superficial fungal infection in atopic dermatitis patients is higher than that in controls. Therefore, we should consider the presence of combined superficial fungal infection in recalcitrant atopic dermatitis patients and use antifungal agents for treatment.

Urticaria pigmentosa (UP) is the most common variant of cutaneous mastocytosis. Primarily a disease of childhood, in over one-half of the cases onset is before 2 years of age, and in 90%, the disease is confined to the skin. UP precedes the diagnosis of systemic mastocytosis and is more common in adults than in children. Therefore, systemic examination should be performed in patients with UP. We report a case of adult-onset UP with systemic involvement.
